just a quick question before bedtime,when your applying to a job and you get to the past employment section do you put down all your past jobs let's say you had about 7 and cant remember the names of the boss and info? I only had two past jobs but I'm just asking cause some ppl I know don't put them all when they check your info can they see your past jobs is it best to just put them I know you need some to show experience
